Manrose XF100AT 100mm Bathroom Extractor Fan with Automatic Shutters and Timer – 4 Inch, White

4 Inch Axial Extractor Fan with Thermo-Activated Shutters and Adjustable Run-On Timer

The Manrose XF100AT 100mm Bathroom Extractor Fan with Automatic Shutters and Timer is a practical ventilation solution designed to remove moisture, steam and unwanted odours from bathrooms, toilets, utility rooms and other suitable domestic spaces.

Manufactured by Manrose, the XF100AT combines reliable axial extraction with thermo-activated automatic shutters and an adjustable run-on timer, helping maintain effective ventilation after the fan has been activated.

Part of the Manrose automatic shutter extractor fan range, the XF100AT features a compact 100mm (4 inch) outlet and is designed for wall, ceiling or window mounting, subject to the appropriate installation accessories and mounting arrangements.

One of its key features is the integrated thermo-activated shutter mechanism.

The shutters are positioned behind the interior grille and open automatically approximately 45 seconds after the fan is switched on.

This provides a convenient shutter arrangement without the need for manual operation.

When the fan is switched off and the shutter mechanism has cooled, the shutters close automatically, helping reduce unwanted draughts through the ventilation opening.

The adjustable run-on timer allows the fan to continue operating after the control signal has been switched off, helping remove residual humidity and odours.

With a maximum timer setting of 20 minutes, the XF100AT is particularly useful in bathrooms where moisture can remain in the air after showering or bathing.

The fan delivers an extraction rate of approximately 85m³/h, equivalent to around 23.6 litres per second, providing effective intermittent ventilation for appropriately sized rooms.

Its 20W single-phase induction motor incorporates pre-oiled bearings designed for long-term operation with minimal maintenance.

The fan housing is manufactured from high-gloss ABS thermoplastic, providing a durable, easy-to-clean white finish suitable for modern bathrooms and utility rooms.

With an IPX4 ingress protection rating, the Manrose XF100AT is protected against splashing water, making it suitable for appropriately positioned bathroom installations.

Operating at approximately 41dB(A) at 3 metres, the fan provides practical extraction performance for everyday domestic use.

The unit measures 163mm wide × 163mm high × 108mm deep and incorporates a 100mm diameter spigot for connection to compatible ventilation ducting.

Backed by a 3-year manufacturer's warranty, the Manrose XF100AT Automatic Shutter Bathroom Extractor Fan is a reliable choice for domestic bathroom ventilation, refurbishment projects and replacement fan installations.

Thermo-Activated Automatic Shutters

One of the standout features of the Manrose XF100AT is its integrated thermo-activated automatic shutter system.

Unlike a basic extractor fan with a permanently open ventilation path, the XF100AT incorporates internal shutters positioned behind the front grille.

These shutters are designed to open automatically when the fan operates.

How the Automatic Shutters Work

When the fan is switched on, the thermo-activated mechanism begins operating.

After approximately 45 seconds, the internal shutters open to allow extracted air to pass through the ventilation outlet.

When the fan is switched off and the shutter mechanism cools, the shutters close automatically.

Benefits of Automatic Shutters

• Automatically open during fan operation
• Close when the fan is no longer operating
• Help reduce unwanted draughts
• Help limit reverse airflow when closed
• No manual shutter operation required
• Convenient for bathrooms and utility rooms
• Integrated behind the interior grille
• Suitable for intermittent ventilation

Why Are Automatic Shutters Useful?

Extractor fans create an opening between an indoor room and the external ventilation route.

Without suitable shutters or backdraught protection, unwanted air movement may occur when the fan is not operating.

The XF100AT's automatic shutters help reduce this effect.

Important: The shutters do not open immediately when the fan starts. The manufacturer specifies an opening delay of approximately 45 seconds.

The shutters should not be described as providing a completely airtight seal.

Adjustable Run-On Timer – Up to 20 Minutes

The Manrose XF100AT incorporates an adjustable run-on timer.

This allows the extractor fan to continue operating for a selected period after the external control signal has been switched off.

The timer helps remove residual moisture and odours that may remain after bathroom use.

• Timer Function: Adjustable Run-On
• Maximum Timer Setting: 20 Minutes
• Control Type: Run-On Timer
• Operating Mode: Intermittent

Benefits of the Run-On Timer

• Continued extraction after bathroom use
• Helps remove residual steam
• Helps reduce lingering odours
• Supports effective moisture management
• Convenient for everyday use
• Adjustable to suit ventilation requirements
• Reduces the need for manual fan operation

Ideal for Bathrooms and Shower Rooms

Moisture can remain in the air after a shower or bath.

The run-on timer allows the fan to continue extracting air after the room has been vacated, helping reduce residual humidity.

This can be particularly useful in bathrooms without opening windows or where natural ventilation is limited.

Important: The fan requires an appropriate electrical control arrangement for timer operation. Installation should follow the manufacturer's wiring instructions.

Why Is Extraction Important?

Bathrooms and utility rooms can generate significant amounts of moisture.

Without effective ventilation, excess humidity may contribute to condensation on windows, mirrors, walls and other surfaces.

A correctly installed extractor fan helps remove moisture-laden air and replace it with fresh air through the building's ventilation provision.

Important: The quoted airflow is a product performance figure. Actual installed airflow can be lower depending on duct length, bends, grilles and other system resistance.

100mm / 4 Inch Axial Extractor Fan

The Manrose XF100AT uses a 100mm axial fan design.

Axial fans move air along the direction of the fan's rotating axis and are commonly used for domestic ventilation applications.
